While the wealthiest took a big hit during the financial crisis, they’ve almost fully recovered. Last year, income for the top 1 percent of earners “increased sharply,” the report notes, growing by nearly 20 percent, while the bottom 99 percent only saw money rise by 1 percent. “In sum,” the authors write, “top 1% incomes are close to full recovery while bottom 99% incomes have hardly started to recover.”

This follows a trend since the recovery officially began. From 2009 to 2012, income for the 1 percent grew by 31.4 percent, while everyone else only saw it grow by 0.4 percent. That means the 1 percent “captured 95% of the income gains in the first three years of the recovery,” they write.

The authors point out that rather than the Great Recession helping to mitigate income inequality, which has skyrocketed since the 1970s, it only temporarily disrupted a trend that is now continuing. And policy isn’t helping. Given that recessions only have a temporary impact on top earners “unless drastic regulation and tax policy changes are implemented and prevent income concentration from bouncing back,” the United States would have to aggressively implement changes that could reverse the trend. That’s what happened after the Great Depression, when the New Deal was enacted. But the response to the Great Recession, which mostly amounted to the Dodd-Frank financial reform bill and an increase in the top tax rate, “are modest relative to the policy changes that took place coming out of the Great Depression,” they write. It’s unlikely they will make any lasting change.
